2.2 Feature description

The Dräger Oxyboks K 35 A is an oxygen self-rescuer, independent of

the ambient air, with a closed to-and-fro breathing system which uses

chemically-bound oxygen.

The Dräger Oxyboks K 35 A is equipped with an additional bump

protector. The bump protector protects the oxygen self-rescuer against

mechanical strength and impact like hits, bumps, abrasing etc. while

using daily. The bump protector is exchangeable.

The Dräger Oxyboks K 35 A has a nominal usage period of

25 minutes. The usage period can be significantly extended

depending on the users breathing rate.

The Dräger Oxyboks K 35 A is carried on a belt on the right or left hand

side of the body.

Use

3.3.6 Fixing straps of the housing

The fixing straps (1) can be shifted

down in the bump protector.

3.4 Important Rules for Escaping

Start the escape calmly, do not rush.

Plan your escape route, choose the shortest way to safe ambient

air!

Behave calmly. Short, quick breaths use more oxygen!

Always make sure that the mouthpiece is tight between your teeth

and lips and cover the mouthpiece tightly with your lips.

The air from the oxygen self-rescuer is warm and dry. This shows

that the oxygen self-rescuer is functioning correctly. A possible

strange taste is normal and harmless.

Do not damage or compress the breathing bag, otherwise vital

oxygen is lost.

If you need to vomit, take the mouthpiece out of your mouth and

close it with your thumb. Do not vomit in the oxygen self-rescuer!

In order to ensure that no harmful air is inhaled from the environ-

ment, do not inhale from the oxygen self-rescuer until the mouth-

piece is reinserted.

3.5 End of Use

When breathing becomes more difficult and the breathing bag begins

to deflate, the oxygen supply is coming to an end.

Any oxygen self-rescuer used underground must be brought to the

surface.
